flight at points a safe distance from avionics antennas to prevent radio frequency interference. Figure 11-161. A typical antenna mounting template. 3. Install the antenna on the fuselage, making sure that the mounting bolts are tightened firmly against ... between the mast and the fuselage with a suitable sealer, such as zinc chromate paste or equivalent. The mounting bases of antennas vary in shape and sizes; however, the aforementioned installation procedure is typical of mast-type antenna installations. Transmission…

different VOR. In most cases, the UHF of the DME is transmitted and received via a small blade-type antenna mounted to the underside of the fuselage centerline. [Figure 11-121] A traditional DME displays the distance from ... antenna 4–7 miles from the approach runway transmits a 75 MHz signal straight up (left). Aircraft mounted marker beacon receiver antennas are shown (center and right). Figure 11-119. A VOR with DME ground station. Figure 11-120. Distance…

type antenna such as that used in ADF. [Figure 11-144] Some lightning detectors make use of the ADF antenna. The range of the lightning strike is closely associated with its intensity. Intense strikes are plotted as being close ... similar Figure 11-143. A typical on-board weather radar system for a high performance aircraft uses a nose-mounted antenna that gimbals. It is usually controlled by the inertial reference system (IRS) to automatically adjust for attitude changes during…
